Similar reference characters refer to similar parts throughout theseveral views of the drawmgs.

Having reference now to the drawings, there .is generally indicated atID a motor vehicle of any desired type, and provided with'a truck' bodyll, within which is contained a turbine or similar pumping device,generallyindicated at 12, and including a casing with rotor i 3 therein(see Fig. 4), and having an inlet l4 in alignment with the vehicle bodyand an outlet l5, preferably extending through asuitable opening in theroof of the truck body I l. The turbine I3 may be driven by the motor ofthe. vehicle, or in any other desired manner. Adoor lB'is the side ofthe body II provides access to the 'turbinefor repairs'as maybenecessary.

Suitably secured to the inlet l4 of'thetturbine is a tubularventilatingmember l8, comprised of canvas, fabric, or rubber tubing, having aplurality of metallic reinforcing ringsi9 positioned interiorly thereoffor the purpose ofniaintaining the same in expanded position whensuction is exerted therethrough "by means of the exhaust turbine l2. Asbest shown in Figures 6 and 7, the outer extremity of thetube I 8terminates in a rectangular member or plate 20, provided with a circularaperture 2'l, to which the outer end of the tube i8 is adapted tobesecured. The member or plate 20 is provided on its inner side withoppositely disposed handles 22, that is, on the side adjacent the tubeI8, and on its outer side adjacent the upper extremity thereof with apair of angularly disposed extending prongs 2 3, the purpose of whichwill bemore fully discussed hereinafter. A bracket'member '24'isprovided on the lower extremity of the member 20 beneath the tube [8.

Means are provided for securing the tube I8 and its associated endmember 20 in relatively close juxtaposition 'to the inlet of the turbinel3,

such means taking-the form of arcuate members 25 pivoted at'threepoints, as at 26, to the front wall of the turbine casing. The members25 are positioned, as best shown in Figure 5, at a substantially spaceddistance from the inlet 14 inorder that the entire length of the tubing,when contracted, may be contained therewithin, and the extremities 210ithe arcuate members 25 engage over the edges of the member 20. In orderto facilitate free pivotal movement of-the members 25 and provide alocking device, extensions 29 extend therefrom to the pivot points 26,and the central extension 29 is pivoted, as .at 30, to each of thearcuatemembersVZS. Extensions 29 are slidable friction clamps forsecuring arcuate members 25 in any desired position. It will now be seenthat when the members 25 are moved from the positions disclosed inFigure 11, the member 20 being retained therebehind, that the entiretube assembly may be contained within the body ll of the truck. Thespecific structure of the sliding clamp means may be seen best in Figure13, wherein there is disclosed a rod 3| slidably received andfrictionally retained in a tube 33. The tube is pivoted at 26 tosuitable brackets, while the rod 31 is pivoted to the aforementionedmember 25. Friction between the telescopic members 3| and 33 retains thearcuate member 25 in a selected position. It will be seen,correspondingly, that any desired length of the tube l8 may be removedfrom the vehicle by displacement of the members 25, and, after thedesired amount has been paid out, the members 25 moved inwardly to theposition disclosed in Figure 4, and clamped between any two of the ringsI9, thus retaining the balance of the tube within the truck body.

When utilized alone, as in conjunction with a small window, or the like,the member 20 is placed within the window, the handle 22 being utilizedfor such purpose, and the projections 23 engaged beneath the upper sillthereof, and the lower portion thereof held in position, as by means ofa spike or the like inserted in the bracket member 24.

Means are also provided for utilizing the device in association with alarge door, or the like,

such means taking the form of a supplemental door .or mounting frame35(see Figures 2 and 3), provided adjacent its upper portion with anaperture 36, extending into which are lugs 31 adapted to engage theupper extremity of the member 20. The mounting frame 35 is provided withelongated'handle members 38 adapted forthe suitable positioning of thesame; and has, in'its lower portion below the aperture 36, a hinged door39 to permit access to the building, or the like, within the center ofwhich is hinged a smaller 'door 40 of a dimension to permit theinsertion of a fire hose nozzle, or the like. Suitable latch means 4|are provided for holding the door 39 in closed position; Means are alsoprovided for securing the mounting frame 35 within a door frame, or thelike, and such means take the form of hook members extending through theinner side of the door through suitable apertures, of a relatively greatlength in order to accommodate varying thicknesses of wall. The innerthreaded portions are provided with rotatable wheels 46, adapted to betightened when the hooks are flared outwardly in desired position withinthe door frame to hold the same in relatively tight related assemblywith relation thereto.

Asb'est shown in Figures 9 and 10, means are provided forextending theheight of the door in order to fully close relatively high door frames,such means taking the form of an extension 49, provided with dependingtongue portions adapted to engagein suitable brackets 5! on the upperextremity of the mounting frame 35.

When it is desired to remove smoke or gas, or similar fumes from abuilding, the frame 35 is first removed from the rear of the truck withwhich it is normally associated, the truck being moved as close to thebuilding as convenient, and secured in position either with or withoutthe extension 49, by means of the hooks 45. The truck is then moved to asuitable distance, the tube I8 being paid out as the truck moves away,or alternatively previously fed out by hand, as may be most expeditious,and when suitably tautened at a requisite distance from the building,the exhaust turbine is started and a powerful suction set up within thetube, and, correspondingly,

is of sufficient dimensions to admit a man into the. building whiletheframe is in place, while the door 30 is of .sufiicient dimensions'topermit the passage of afire hose readily therethrough.C'orrespondingly, as above pointed out, in the event that only a smallaperture is available, the member or plate 20 maybe utilized alone, by

i detaching the same from theunountin'g. frame 35.

From the foregoing, it will now be seen that there is herein provided animproved mechanical ventilator readily transportable, and adapted forthe ready ventilation and removal of fumes, gases, smoke, or the like,from any desired location, Which accomplishes all of the objects of thisinvention and others, including many advantages of great practicalutility and commercial importance.

As many embodiments may be made of this inventive concept, and as manymodifications may be made in the embodiment hereinbefore shown anddescribed, it is to be understood that all matter herein is to beinterpreted merely as illustrative and not in a limiting sense.
